是否有一种简单的方法可以在python中修剪视频文件。如果我知道开始时间和结束时间,我想根据输入将新文件保存为多个较短的文件。
示例伪代码:
function cut_video(original_vid, start, stop):
original_vid.start_time(start)
original_vid.end_time(stop)
original_vid.trim() #based on times
new_vid = original_vid
return new_vid

找到解决方案:
def get_ffmpeg_bin():
ffmpeg_dir = helper_functions.get_ffmpeg_dir_path()
FFMPEG_BIN = os.path.join(ffmpeg_dir, "ffmpeg.exe")
return FFMPEG_BIN
def split_vid_from_path(video_file_path, start_time, durration):
ffmpeg_binary = get_ffmpeg_bin()
output_file_name = get_next_file_name(video_file_path)
pipe = sp.Popen([ffmpeg_binary,"-v", "quiet", "-y", "-i", video_file_path, "-vcodec", "copy", "-acodec", "copy",
"-ss", start_time, "-t", durration, "-sn", output_file_name ])
pipe.wait()
return True
sample_vid = os.path.join(get_sample_vid_dir_path(), "Superman-01-The_Mad_Scientist.mp4")
split_vid_from_path(sample_vid, "00:00:00", "00:00:17")

电影是完成这些任务的一个不错的模块。
示例代码:
from moviepy.editor import *
video = VideoFileClip("myHolidays.mp4").subclip(50,60)
# Make the text. Many more options are available.
txt_clip = ( TextClip("My Holidays 2013",fontsize=70,color='white')
.set_position('center')
.set_duration(10) )
result = CompositeVideoClip([video, txt_clip]) # Overlay text on video
result.write_videofile("myHolidays_edited.webm",fps=25) # Many options...
